Introduce a priority for bus-probing functions

We want to stop probing once anything was detected by specific,
high-priority probing functions. This can benefit, for example,
the probing of non-flash chips on the SPI bus. So far we didn't
probe for these automatically, because the probing commands can
be misunderstood by SPI flashes.

We'll invoke the probing functions in order of their priority,
starting with priority `0'. Once any of them returns something
that doesn't look like continuous 0 or 1 bits,  we'll skip all
probing functions with less priority.
